摘　　要：为了改善竹炭板外观质量、提高其力学性能、拓展其使用范围。实验以竹炭板为基材,选取科技木皮、竹皮和浸渍纸3种贴面材料,异氰酸酯双组份胶黏剂,采取冷压工艺,按照正交试验方法进行试验,并采用红外光谱分析其结合界面,结果表明:(1)3种贴面材料的最优工艺范围:涂胶量110~130 g·m^(-2),预固化时间5~10 h,冷压时间1.5~3.5 h,冷压压力1~2 MPa。(2)贴面后的竹炭板抗弯强度与弹性模量增长较为明显,含水率、吸水厚度膨胀率、尺寸稳定性等性能均符合GB/T 24137-2009《木塑装饰板》规定的要求。(3)通过红外光谱图谱分析可知,胶黏剂与竹炭板界面、木竹材界面均通过物理结合,而与浸渍纸界面通过化学结合。In order to improve the appearance quality of bamboo charcoal board,enhance its mechanical properties,and expand its range of use,an orthogonal experiment was conducted,in which,the bamboo charcoal plate was used as the base material,the technological wood veneer,bamboo skin and impregnated paper were selected as cover materials,the isocyanate was used as adhesive,the cold-press process was adopted,and the infrared spectrum was used to analyze the interface.The results showed that:(1)the range of three kinds of optimal technology of surface lining was as follows:gelatinizing volume 110-130 g·m^(-2),curing time 5-10 h,cold pressing time 1.5-3.5 h,cold pressing pressure 1 to 2 MPa.(2)the bending strength and elastic modulus of the bamboo charcoal board increased significantly after veneering,and the performance of water content,water absorption thickness,expansion rate,dimensional stability and other properties were in line with the requirements of GB/T 24137-2009"Wood Plastic Decoration Board".(3)through infrared spectrum analysis,it can be seen that the adhesive was physically combined with the interface of bamboo charcoal board,wood and bamboo wood,and chemically combined with the interface of impregnated paper.
